In his new novel, “Twist,” the National Book Award-winning Irish writer Colum McCann tells the story of a journalist deep at sea in more ways then one: A man adrift, he accepts a magazine assignment to write about the crews who maintain and repair the undersea cables that transmit all of the world’s information. Naturally, the assignment becomes more treacherous and psychologically fraught than he had anticipated. On this week’s episode, McCann tells host Gilbert Cruz how he became interested in the topic of information cables and why the story resonated for him at multiple levels.
